For this week’s Galaxy S2 GT-i9100 ROM of the week, check out the latest Biftor ROM version 10.

UPDATE: Version 12 is OUT, CLICK HERE to see it instead of this older version!

Better than ever, latest Biftor ROM comes with a completely revamped Biftor ROM Control Settings that allow you to tweak every part of your Galaxy S2 including your status bar, lockscreen, battery, signal, and even change the colors of each parts. Of course, there’s even more cool stuff like auto call recording settings, soft navigation buttons, and much more.

Other notable feature include Kill App button (menu or back button), lockscreen torch, 6 different lockscreens, lots of wallpapers, scrolling wallpaper, launcher rotation, and even more.

Overall, I am impressed by the integration of Biftor ROM Control Settings that provide many more customization/settings than ever before and also working stable out of the box.

It’s probably safe to say Biftor ROM is one of the best ROMs for the GT-i9100 so if you haven’t tried the latest version, definitely give it a go this week(end) and do let me know what you think!

  • truongdt

    By the way, you can show me how to use the NFC on S2-I9100G? I use rom stock jb 4.1.2.

  • extraaworks

    I used v9 and v10 both.
    I liked the customization provided in the rom.
    But unfortunately,I found both very buggy.
    Every 5-10 secs i was getting “Unfortunately, system UI stopped responding” error message.
    Even when I am just scrolling setting menu.
    If you change color or any customize anything and restart anything(status bar..etc), system stops responding.

    • ike

      I also installed from Snapdragon S2 rom. After changing the system notification to my liking, it was error, error, error after 5 seconds. flashed back to Snapdragon S2. will try next good rom. This one is buggggy

      • Andy

        make a full wipe.. factory reset. backup your app using titanium backup.. install rom then restore app using titinaum bckup.. i hope its never lagg.. cuz i been using this rom 3 month never have bad issue πŸ˜€

    • Goran Leskov

      I didn’t have your problem with rom, did you do FORMAT SYSTEM, DAVLIK, CASHE partition AND DATA format before install.
      I did all of that even without data format everythig worked fine , my only problem is the ram usage, ity uses a lot of ram, more than my ics which I still use.

  • Justin

    Downloaded this rom and I love it… Followed the directions for my sgh-1777 and everything works fine, except for the phone!! Anybody else having this problem? Cant hear anybody and nobody can hear me at all. I can text, I can do EVERYTHING, except use the actual phone function. Any Help?

  • Chrisss5000

    Hi the stock music player dosen’t work at me please!

  • sakkie

    This rom is a battery thieve it chows batteries for breakfast !! It also reminds me of a cheap 10 cent store totally overcrowded with to much colors and functions ! Wallpapers are nice so is the record function in the dial pad. Dev could easily half the functions.

  • Mr.Tony

    Flashed it successfully on my SGH-I777, everything is smooth ,now testing the battery ! So much options in this ROM.
    Niiiice! πŸ™‚

  • Krasy

    is it just me or no mail or exchange apk?

  • Goran Leskov

    Hi, I have tried almost every rom you posted, I like biftor rom a lot IT’s the best JB:) but the only thing I do not like is the ram memory which it has, I have on my ICS Omega rom around 550 mb of ram full with running apps that I use on iddle, and on a biftor rom 700mb something ram with same my apps, do not lke that. Is there a way to make it more ram friendly. And thanks for all the roms you tested, you helped me a lot with testing roms for my s2. Keep it up πŸ™‚

  • kai

    I’m sure you are also looking for a good jelly bean rom for your SGS2 GTi9100, based on stock but clean, slim, battery-friendly and stable as a mountain. I have tried them all: Omega, Snapdragon, RainboxRom, NeatRom and this one Biftor. They are all buggy, unstable, fat, and battery and/or ram hungry.
    There is only one out there that definitely stands out from the mass: Chameleon ROM v3.0.2. Though the upgrade version 3.0.3 isn’t as stable as its predecessor, version 3.0.2 is absolutely worth a try. Check the features.

    • slasher1986

      I have found no bugs with omega v22-v23 or v24. I find them extremely stable and fast and have used omega for a long time now and will encourage anyone that owns an s2 to flash it. When I comes to Biftor, if you found its predecessors unstable stay well away.

      • kai

        You will encourage anyone that owns an s2 to flash Omega and who doesn’t care about battery life…

        • slasher1986

          my battery has bean going for 14 hours and I still have 43% can’t get better then that

          • kai

            Yes, that’s right. I had also about 50% of battery with my mobile running for about 12 hours. That’s usual for Omega, Biftor, NeatROM, etc. but I suggest you to take a look to Chameleon. A full battery lasts for about 45 hours. No kidding!. Of course, provided you don’t abuse :-). Give it a try!. I don’t say Chameleon 3.0.2 is perfect but it has most of what a normal user desires for custom rom with samsung functionalities.

            • slasher1986

              I will try it out : )

              • slasher1986

                have you got a download link? : )

                • kai

                  Of course:
                  If this link doesn’t work, just google “Chameleon ROM xda developers”. Check the features first, follow the instructions and do a CLEAN installation. DO NOT flash the last version 3.0.3, which is an upgrade and it is unfortunately not as stable as version 3.0.2. Enjoy! πŸ™‚

                • Noel

                  Google “Chameleon ROM in xda developers”. Check the features, follow instructions, do a CLEAN installation. DO NOT flash the upgrade 3.0.3 because it is not as stable as the previous version 3.0.2. Enjoy and forget about other samsung based custom roms πŸ˜‰

                  • slasher1986

                    thankyou mate: )

  • kai

    @ slasher1986
    Of course!
    Check the features, follow instructions, do a CLEAN installation. DO NOT flash the upgrade 3.0.3 because it is not as stable as the previous version 3.0.2. If the link above is erased here or doesn’t work, google Chameleon ROM in xda developers. Enjoy and forget about other samsung based custom roms πŸ˜‰

  • jteles

    Hey guys, what’s up? I’ve got a question.
    To install a ROM on my S2(GT-i9100), should it be in a specific
    ANDROID version(mine is 4.0.3) or being in any is OK ?


  • luvis

    Hey there, nice rom πŸ˜‰
    Is there any bugs in this rom ?
    im using 4.1.2 root right now, so i can just install it straight away ?
    any kernel for this ?

  • IanH

    ROM looks good, lots of stuff in there but I immediately notice that I can’g connect to my office Exchange Mail any more, only Gmail available. And Titanium restore of the email and exchange services just fails.

    Any ROM that can’t support my work email is useless to me no matter how good the other features are. Any suggestions? I don’t particularly want to use K9 tried it on mt tab, didn’t like it and forgot why, the stock android app was fine

  • slasher1986

    I like this ROM but only for the gallery. just find myself going back to omega v24 the most stable ROM out there in my opinion. sorry biftor

  • slasher1986
